REVERSIBLE PLOW.

SPECIFICATION forming part of Letters Patent No. 709,439, dated September 16, 1902.

` Application ined April 4., 1902. serial No. 101,394. or@ model.)

. a citizen of thejUnited States, residing at Dublin, in the county ot' Pulaski and State i `of Virginia, have invented a new and useful Reversible Plow, of which the following is a` specification.

My invention is an improved reversible plow adapted for use in plowing hillsides and for other purposes; and it consists in the peculiar construction and combination of devices hereinafter fully set forth 'and claimed.

In the accompanying drawings, Figure 1 is a side elevation of a reversible plow embodying my improvements. Fig. 2 is a vertical transverse sectional view of the same, taken on a plane indicated bythe line a d of Fig. 1. Fig. 3 is a detail horizontal sectional view of the same, taken ou a plane indicated by the line b o of Fig. 2. Fig. 4 is a detail perspective view of one of the frames to which the front portions of the moldboards are bolted. Fig. 5 is adetail vertical sectional View showing the clevis and the means for shifting the same laterally. Fig. 6 is ay detail top plan` View of the same.

In the embodiment of my invention 1 provide the beam V1 with a reduced cylindrical portion 2 at a suitable distance from its rear end, which cylindrical portion forms a neck on which a double reversiblestandard 3 has its bearings, the said"f reversible standard being provided on one side at its center with a detachable bearing block or section 4, which is here shown as secured to the integral portion of the reversiblestandard by bolts 5. A xed standard 6 depends from the beam at a point immediately in advance of the reversible standard 3. A forwardly-inclined brace 7 is here shown as connecting the beam to the fixed standard, at a point a suitable distance from the' upper end of the latter. To the lower end of the fixed standard is secured the longitudinally-disposed footpiece 8, on the lower side of` which is bolted a removable sole-plate 9, thelatter having a-shoulder 10 on its upper side, near its front end, which shoulder engages the front end of the footpiece 8. On the rear portion of the footpiece is a housing 11, which is bolted on the footpiece by the same bolt 12 which also secures the rear end of the sole-plate to the under rear side.

side of the footpiece. The sides 13 of the housing are flush with the side edges of the Vfootpiece and sole-plate, and the front end of Vthe housing is disposed at such distance in rear of the fixed standard 6 as to clear the reversible standard 3, so that theopposite ends of the latter may be alternately disposed between the housing and the fixed standard in order to bring either of the plowshares carried by the reversible standard into position for operation. The sides ofthe housing form'portions of the sectional landsides, as do also the sides of the fixed standard 6, if the latter is of iron or steel. It said fixed standard 6 is a wooden standard, its sides are covered at its lower portion with sectional landside-plates 14, as shown in the drawings. The front ends of the handles 15 are secured to the inner sides of the vertical walls of the housing by a bolt 16. The cross-bar 17, (shown in dotted lines in Fig. 1,) which connects the handles 15 together, is secured to the beam at or near its rear end, a clip-bolt 18 being shown in Fig. 1 for this purpose.

The reversible standard 3 carries plowshares 25, which are reversely disposed and are identical in construction. The following is a description of one of them: A frame 19 has its rear side vertical, as at 20, and its lower side 21 disposed at right angles to its The front side 22 of the said frame is curved to adapt it to to iit and receive the moldboard 23, the cutter or colter 24, and the point 26a. In the construction here shown the cutter 24 is separable from the moldboard, and the bolts which secure it to the moldboard pass through the latter and the curved front side of the frame 19, so that the front portion of the moldboard is clamped between the cutter and the said Within the scope of my invention the cutter may be formed integrally with the moldboard, and I do not limit myself in this particular. The point 26ais provided on its under side with a shoulder 2G, against which the front end of the sole-plateV 9 is adapted to abut. The landside-plate 27 is bolted to the outer side of the frame 19 and is adapted to aline with the sectional landsideplates 13 14, as shown in Figs. 1 and 3. On the inner side of the frame 19 is abridge-bar 28, the same being bolted thereto, as at 29,and the IOO rear end. of the said bridge-bar is bolted to one side of the reversible standard 3. The said bridge-bar is adapted to bear against the inner side of the fixed standard 6,'and when the latter is turned to dispose the plowshare in position for operation said bridgebar by abutting against the fixed standard stops the rotation of the reversible standard 3 when the latter alines vertically with the fixed standard 6. A brace-strap 30 has its intermediate portion bolted to the inner side of the moldboard, at a suitable distance from the rear end of the latter, has one end bolted on the bridge-plate, as at 3l, and has its opposite end secured on one ot' the bolts 5, which are employed to secure the removable bearing-section 4 in place.

The intermediate bearing portion of the reversible standard 3 is provided on its rear side with an annular flange or-collar 32. The same has on opposite sides notches 33, which are coincident with the major axis of the reversible standard, and the said notches are adapted to be engaged by a gravity-detent 34, which is pivotally mounted on the upper side of the beam, as at 35, the said gravitydetent by engaging one of the notches 33 ,serving to lock the reversible standard in a vertical position with one of its plowshares disposed in operative position on the footpiece S. In the rear side of the reversible standard, near the ends thereof, are notches 36. The same are adapted to successively register with the housing 11, and in the latter and pivotally mounted on the bolt 16 is a gravity-detent 37, the front end of which is adapted to engage the said notches 36 to lock the reversible standard at its lower end. A rod 38 connects the detents 34 and 37. The latter has a rearwardly-extending arm or pedal 39, adapted to be pressed by the foot of the operator, and it will be understood that when the detent 37 is disengaged from the lower end of the reversible standard the detent 34 willbe simultaneously disengaged from the intermediate or bearing portion thereof, so that said standard may be turned to reverse the plowshares.

At the front end of the beam 1,'on opposite sides thereof', are vertically-disposed plates 40, the front ends of which project in advance of the beam and are provided with a vertical series of adjusting-openings 41. Said plates 40 are secured to the beam by any suitable means, bolts 42 being here shown for this purpose. A clevis 43 has an axial support 44, which is adapted to be disposed appropriately in the adjusting-openings 41 at any desired height, so that the clevis may be supported at any desired vertical adjustment, and the said axial support 44 adapts the clevis to be shifted laterally between the plates 40, so that the clevis may be adjusted in such manner as toconnteract any tendency to side draft and to adapt the same to work in connection with either of the reversible plows. The clevis is here shown as provided at its upper and lower sides with rearwardly-extending ears l45, which are connected together by a vertically-disposed bolt 46. On the upper side of the beam, near the front end thereof, is a bell-crank 47, which is here shown as pivoted on a bolt 48, that extends through an opening in the plow-beam. l The front end of the lon gitudinally-'extending arm of said bellcrank is provided with a slot 49 to receive the bolt 46. The laterally-extending arm of the bell-crank is connected by a rod 50 to a handlever 51, which is fulcrumed to the beam, as at 52. A dog 53 and a segment-rack 54 are provided to secure the lever 5l at any desired adjustment. It'will be understood that the clevis may be shifted laterally by operating the lever and that by appropriately locking the latter the clevis may be maintained at any desired adjustment.

Having thus described my invention, I claim- 1. In a reversible plow,the combination of a beam having a xed standard and a footpiece at the lower end of said standard, a reversible standard pivotall y mounted on said beam and shares carried by said `reversible standard, said shares being adapted to bear successively on the footpiece and having stops to aline their landside-faces with the sides of the fixed standard, substantially as described.
